UNITED STATES PATENT OFFICE.

JOHN BOYLE, on NEW YORK, N. Y.

lMPROVEMENT IN THE MANUFACTURE OF BOOTS AND SHOES.

Specification forming part of Letters Patent No. 141,257, dated July 29,1873; application filed June 21, 1873.

To all whom it may concern:

Be it known that 1, JOHN BOYLE, of the city, county, and State of NewYork, have invented a new and Improved Clamp for Attaching Textile orother Fabrics to Wood or Composition Soles, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a side view of a shoewith my improved clamp for connecting the upper part to the sole, partlyin section. Fig. 2 is a bottom view; and Fig. 3 is a detail verticalsection of the same, showing the shape of the binding-clamp.

Similar letters of reference indicate correspondin g parts.

The object of my invention is to provide an improved clamping-connectionof textile or other fabrics with hard and unyielding materials, as woodor composition soles, 860., so that shoes or other articles ofmanufacture may be produced quicker and cheaper by means of suitablemachinery, and the hand-labor, hitherto necessary for such work, bedispensed with. My invention consists in grooving the wood sole or othermaterial at the upper edge, and binding the fabric, by a suitably-shapedmetallic clamp, firmly thereon, so that a strong and intimate connectionof the parts is obtained.

In the drawing, A represents the sole, to which the textile or otherfabric is to be attached. It is made of wood, composition, or othersimilar material, and provided, along its upper edge, with a groove, a,of semicircular or other shape. The upper part B of the boot, shoe,850., is made of textile fabric, leather, rubber, or other similarmaterial, and applied to the sole A by means of a clamp, U, which runsalong the edge of the upper B, covering the same, and fitting accuratelyinto groove a. Clamp G is produced either of wire of suitable thickness,which is formed into the required shape, or stamped of sheet metal. Theupper part or head of clamp O is of round or other shape, correspondingto that of groove a, with slightly-tapering lower edge, as indicated inFig.3, which serves to protect and bind the edge of upper B.

The clamp is made of such length and width that when applied to connectthe sole A and upper B, by suitable machinery, it will accurately fitthe groove of the sole the increased length required for the curved partbeing obtained by the gain in length along the circumference of thegrooved or recessed part of the sole.

The clamp 0 forms asolid compact connection with parts A B withoutprojecting beyond either, and combining it in a stronger, more even, anddurable manner than if nails, rivets, or other connection had beenapplied.

Having thus described my invention, I claim as new and desire to secureby Letters Patout-- In combination with textile or other similar fabricB, and a grooved or recessed sole, A, the binding-clamp (J, forattaching the fabric firmly thereto, substantially as described.
